This invention relates to locking mecha# nism for doors and moreparticularly to such mechanism wherein there are employed a releasablelatch and an additional bolt as a *o night lock. p

One of the objects ofthe invention is to provide av mechanism of theabove nature which is practical and efficient and capable of meeting therequirements yof use in a highly satisfactory manner. Another object is`to Y provide a devicer of the above vnature which is capable of a widerange of use `under varying conditions. Another 'object is to provide adevice of the above nature which is simple 1'5 andy which" is capable otbeing mounted in operative position with theigreatest conven.- ience andwithouttheneed of undue alterations or'adjustments to meetvaryingcondi-l tions.v Another object isto provide a device i 2O-oftheabovenature ywhich* is strong and dependable. Other objects will bein part obvious or in part pointedout hereinafter."

The invention accordingly consists in the features ofconstruction,combinations of ele- 5 ments, and arrangements of parts aswill be exemplified in the structure to be hereinafter described andtheis'cope of the applicationot which will ybe indicated in thefollowing claims; A 4f Y f y In the accompanying drawings in' which isshown one of the-variouspossible embodi-y ments of this invention," YFigure 1y is ay front-view of the lock mecha,- nism in operativepositiomthe Vdoor vframe and parts of the mechanism being'brolen away todisclose the inner structure; Y

the door Figure 2 is anelevation viewing Jframe edgewise;

c Figure 3 is a perspective ofthe door frame portionshown in FigureQ;Figure 4 is a view similar to Figure 3 and showing the same lockingmechanism applied to a door frame wherein the door kswings in theopposite direction, and Figure 'is a perspective of certain? parts of.the locking mechanism removed from the door frame. Y 1 f Similarreferencechar'acters refer to similar parts throughout theseveral viewsof the drawings. i

p Referring now tothe drawings in detail and first tollligure l, thereis shown a door 10 adapted to swing into a door frame indicated at 11and against a stop 11a. The door frame 11 is recessed at 12 toaccommodate axmetal casing J13 which ormsfa part of the lookingmechanism. This casing 13 may be made conveniently of brass and in "theembodiment shown in the drawings it is l a cast1ng,lit belngunderstoodthat the casing might also be shaped lout of sheet metal.

ffidyacent the open outerend ot the casing 13 ismounted thereinr amember 14 which is Aadapted to receive and catch thel-atchl of the door10 and thereby hold the'door closed.

able mechanism contained within the casing 13 whereby it may be moved,by control from i a remote point, to a position in vwhich the latch 15is disengaged,ftherebypermitting opening ofthe door.

ln the embodiment of the latch-releasing mechanismshown in the drawings,the mem; ber ltispivotally mounted upon a vertical pin 16 and is urgedby spring v17 to swing, in they direction indicated bythe arrow inFigure 3, into engagement with thelatch 15.

Two lever arms 18 are pivoted in thecasing 13l and engagewith the memberv11i adjacent their outer ends through pins 19 projecting rom'thetOpandbottom ends of the'member l '14. The inner .ends of the lever 'arms 18normally engage theedge of a plate-like ar-e matureQO'which is pivotedin the casingj13 and which is positioned, therein to be actu- 4This`memberlet is provided .with any suit-` ated by the jelectromagnet 21.Thev coils ofI lthe electromagnet are connectedthrough the bindingpostsk22 to any suitable source of cur i rent'and thr'ough'aswitch which maybe lothe urge of the spring 16 to a position in which the latch isenabled to slip by. It may be here noted that this releasing mechanismis not shown in greater detail since of themselves the specific featuresthereof are unimportant as relating to this invention.

The casing 13 is provided at its front end with right angle extensions24 and 25 in plate form extending out vardly therefrom on opposite sidesthereof; that is, whenfthe lnechanism is in position upon the doorframe, one of these plate extensions projects upwardly from the casing13 and the other projects downwardly therefrom.y The parts 24 and 25preferably are permanently secured to the casing 1,3. They may be madeintegral with the casing if desired, or they may comprise a singleintegral plate secured to the casing 13, for example by welding, and thetwo parts of which are joined by a central portion 26, as best shown inFigures 2 and The parts 24 and 25 are adapted to rest fiatwise againstthe surface of the door frame 11, as shown and preferably the door frameis recessed to receive them. Screws 2,7 passing through the parts 24 and2,5 into the door frame 11 serve to position and hold in place theentire lock mechanism of the door frame.

Referring again to Figure'l, the lock mechanism mounted upon the door 10is provided with a bolt 2.3 in addition to the latch 15. This bolt is inthe nature of al night lock and may be operated, for example, by a thumbknob on the innerside of the door and by a key from the outer side.

In some doors the night bolt 2-3 is positioned below the latch 11i, asshown in the drawing, and in other doors itis positioned above thelatch. The locking mechanism employed upon the door frame hereindisclosed is adapted to meet the requirements in either case. The plateparts 24 and 25 of the casing 13 are preferably substantially identicaland each is provided with an opening therethrough which may receive anight bolt23. As shown in Figure 5, the part 24 is provided with theopening 28 and the part 25 is provided with the opening 29. r

These openings 28 and 29. are furnished with means whereby either onethereof may f be rendered operative or inoperative as desired. Removablemetal pieces 30 and 31 are provided which `fit snugly int-o therespective openings 28 and 29. Preferably these metal pieces and theopenings in which they fit are correspondingly tapered, lbeinglarger atthe rear of the plate than at the front, so that the metal pieces areremovable only from the rear. Thus when the device isk positionedagainst the door frame, the metal piece'whch is left in its opening 4islocked inposition therein by the 4door frame. `The metal pieces larepreferably :of the ,same thickness as the metal of `the plate parts intowhich they fit so that tbesurfaces are substantially flush.

Thus in the door frame shown in Figures 1, 2 and 3, wherein the nightbolt is positioned below the latch, and wherein the door swings asindicated by the arrow in Figure 3 against the stop 11a, the piece 31 isknocked out so that the opening 29 in the part 25 is rendered operativeto receive the night bolt, andthe piece 30 is left in position in itsopening 28 effectively closing this opening and being locked in positionby the door frame against which it rests. If the bolt of the night lockwere above the latch in this door, the piece 30 would be knocked out torender the opening 28 operative and the piece 31 would be left inposition.

Referring now to Figure 4, there is shown a door frame wherein the doorswings against stop 11?) in a direction opposite to the direction ofswing of the door in the preceding figures. In this instance the lockingmechanism of the door frame is simply turned end for end, the part beingnow abovethe latchreceiving means and the part 24 below. If the nightbolt is below the latch the piece is knocked out to render the opening28 operative (as shown in yFigure 4) and the piece 31 is left in. If thenight bolt were above the 'latch the piece 31 would be knocked out andthe piece 30 left in place. It will be seen, therefore, that the lockingmechanism is capable of fulfilling any requirement without being alteredor adjusted and without re-.arrangement of any parts except for simplyknocking out one of the metal pieces 30 or 31 according to the openingto be utilized. These metal pieces may be termed knock-outs.

From the foregoing it will be seen that there is herein vprovided adevice which embodies the features of this invention and achieves theobjects thereof including ad- Y vantages of great practical importance.The devices are preferably furnished with both the pieces 30 andlintact. The carpenter setting upthe locking mechanism has then simplyvto knock out the piece not required in order to fit the mechanism toany conditions which may be met. The plate members 24 and 25 beingpermanently secured to the casing 13, full strength and serviceabilityis assured.

As many possible embodiments may be made of the above invention, andasmany changes might be made in the embodiment above set, forth, it is tobe understood that all matter hereinbefore set forth or shown in theaccompanying drawings, is to be interpreted as illustrative and not in alimiting sense.
